The small crash report is:

The game crashed whilst initializing game
Error: i: Non [a-z0-9/._-] character in path of location: minecraft:blocks/item_frame_sides 2

And this only happens on one account, which I believe is because it is the only one with older versions of Minecraft.

The large crash report is:
